JOHN CHAPMAN, OF ALDRINGTON, ENGLAND.

CARPET-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 590,255, dated Septemb r 21, 1897.

- Application filed January 17, 1896. Serial No. 575,904. (No model.)

To Cl/ZZ whom it may concern.-

Be it known that 1, JOHN CHAPMAN, a subject of the Queen of Great Britain, residing at Aldringt'on, in the county of Sussex, England, have invented certain new and useful Improvements in Carpet-Beating Machines, of which the following is a specification.

In order that my invention may be more readily understood, reference is made to the accompanying drawings, in which Figure 1 is alongitudinal section of my improved carpet-beating machine. Fig. 2 is a transverse section. Fig. 3 is an end elevation. Fig. 4 is an enlarged detail, being an end elevation of the brush-shaft and rack and pinion (s and t) for raising it. Fig. 5 is a sectional plan on line 5 2, Fig. 4. Fig. 6 is a sectional lan on line .2 2 Fig. 4.

The same letters of reference apply in all the figures.

In carrying out my invention I make use of an ordinary structure or erection similar to that at present in use, through the length of which and at a suitable height from the floor is a driving-shaft a, worked by means of fast and loose pulleys b and straps outside the machine. Mounted on this driving-shaft I have a cylinder 0, cast with four flanges d at right angles. The cylinder is preferably made in three equal lengths, although in some machines two and in others a larger number might be used with advantage. These three equal lengths are fastened to the driving-shaft by means of screws, bolts, or keys, or in any other suitable manner. At each end of the three lengths of the flanged cylinder I provide a coupling 6, and when mounted on the driving-shaft the center couplings fit close together and are fastened by means of bolts f. On the side of each of the flanges I place a piece of flat steel plate g the same length as the flange. I bolt the two together somewhat loosely, so that although held together a small space separatesthem. In this space I place one end of the rubber belting 7L or other form of beater which may be employed. It will be observed that the fast end of the belting projects beyond the edge of the metal plate and on the hollow cylinder. The object of this is that when the loose ends are worn out the heaters can all be drawn forward, or, if desired, reversed, by simplyloosing the bolts, thus saving having to replace with new ones. The heaters are arranged so that a small space is left between each, and when suflicient have been placed in position the bolts (which are placed in the spaces between the beaters) are tightened until they are securely fastened.

The improved sloping bed over which the carpet passes while being beaten consists preferably of two rollers 76, fitted through the length of the machine, having suitable bearings, one of'them being placed close to the slot or aperture 772, through which the carpet is passed into the machine, and the other nearer the base and farther from the side of the apparatus. From roller to roller I have at short distances from each other a series of endless straps it, made of rubber belting or any other suitable and substantial material having sutlicient flexibility to prevent the carpet beingin any way injured by the strokes of the heaters. As the carpet is being drawn into the machinebythe action of the heaters the straps of the bed move slowly around, thus giving an equal amount of wear to allthe bed.

Upon a second driving-shaft 0, provided with fast and loose pulleys p, I affix a cylindrical brush r, made of bass or other suitable material. The brush is fitted to be raised or lowered, so that it may be brought into contact with the surface of the carpet y when desired. I The ends of the shaft 0 extend beyond the ends of the machine and traverse radial slots 1) in slotted guide -plates 19, fitted to both ends of the machine. The ends of the shaft 0 rest upon the curved bars 8, which are provided with rack-teeth s and are raised and lowered by the rack-wheels ii. The rackwheels t at either end of the machine are connected to rotate simultaneously by theshaft or rod it. On the rod to is fixed a handle or lever c, by which the wheels If are rotated to raise or lower the brush, and at one side of the handle 1; is placed a rack with which the handle engages to maintain the brush at any desired height.

In working my invention I place the carpet y, Fig. 5, over the roller 2 outside the machine, through the slot or aperture m, and onto the bed 71. The heaters and brush,which are above the bed.

worked by steam-power, are sufficient to draw the carpet forward. when I get to the end of the carpet, I reverse the action of the brush by throwing the driving-belt off the fast pulley and onto the loose one and at the same time bringing into operation the cross driving-belt 0, provided at the other end of the machine. This cross-belt reverses the action of the brush, which not only assists in withdrawing the carpet from the apparatus, but also removes the light dust which always settles on the same as it is being beaten.

It will be understood that the distance between the brush and the bed n can be so regulated as to admit any thickness of carpet by means of the lever w and the rack s before mentioned, and, if desired, can be dispensed with altogether by raising it several inches By using the brush attachment in addition to the heaters the carpet is not only beaten but brushed and saves considerable time, it being possible to complete at one operation what formerly had to be done by manual labor after the beating was finished.

What I claimas my invention, and desire to protect by Letters Patent, is

In a carpet-beating machine the combination in a frame, of the shaft 0 and circular brush 1" mounted thereon, the ends of the shaft traversing curved guides 13 attached to the ends of the frame, the upright bars 5, the upper ends of which form journals for the brush-shaft, the racks s at the lower ends of the bars 8, the cog-wheels 25 by which the bars 8 are raised, the shaft to extending from one end of the machine to the other, and the lever I) for rotating the shaft substantially as de scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN CHAPMAN.
